What is one of the main functions of dietary fiber?

One of the main functions of dietary fiber is to aid in digestion. Fiber plays a critical role in maintaining digestive health by adding bulk to the stool, which helps it move more easily through the intestines. This bulk-forming property can prevent constipation and promote regular bowel movements. Additionally, fiber can help to support a healthy gut microbiome by serving as a food source for beneficial bacteria in the intestine.

Incorporating an adequate amount of fiber in the diet can also help regulate blood sugar levels and contribute to feelings of fullness, which can be beneficial for weight management. These roles highlight the importance of fiber in maintaining overall digestive health and well-being.
